1948 Map of Tustin

About this map

Santa Ana and Tustin anchor the northwestern corner of this mid-century survey, showing the transition from dense urban blocks to the massive agricultural holdings and open ranges of the San Joaquin area. A significant portion of the landscape is dominated by the Naval Reservation, surrounded by private gun clubs like the Twenty Ranch Gun Club and Sprig Gun Club, reflecting a landscape defined by military utility and rural leisure before the suburban sprawl of later decades. The Atchison Topeka and Santa Fe Railroad cuts a diagonal path through the map, serving small transit points like Browning, Frances, and Kathryn. To the south, the terrain rises into the San Joaquin Hills, where vital water infrastructure such as the San Joaquin Dam and Sand Canyon Reservoir support the region's ranching economy, centered on the sprawling Irvine Ranch.
